标题: 脑子进水?请教GWD30-Q9答案问题
Q9:
Is the measure of one of the interior angles of quadrilateral ABCD equal to 60 degrees?
(1)    Two of the interior angles of ABCD are right angles.
(2)     The degree measure of angle ABC is twice the degree measure of angle BCD.

答案是C

为什么我选了E

因为根据题目(1)和(2)放在一起,可能有两种情况
A. 一个梯形,60,120,90,90
B.一个类似扇形,45,90,135,90。
所以我觉得应该是E啊,是答案错了,还是我脑子进水了,请教大牛
